Acornea transplant involves the grafting of a donor cornea into a recipient’s anterior eye. the sutures to hold the graft in place must stay in place for a long period of time because the cornea is slow to heal. explain why the healing process is so slow and also why graft rejection is unlikely with a cornea transplant.

do you have a picture?

the answer is; comparing the frequency of collisions with and without the device

this makes the anti-collision system an independent variable and the collisions a dependent variable. if there are fewer collisions with an anti-collision system that without, then it can be stated that the system is a success. essentially, collisions under an anti-collision system are compared with the frequency of collisions by cars with the human drivers.

genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).
